Lamarck describes three species of this f^eiius, depending on the
general outline and the waved or flat form of the shell, characters
which are liable to considerable variations, as may be found on the
mere inspection of any considerable number of specimens.
The hinge forms a more permanent character, and affords the
means of dividing the species into two sections, and furnishes cha-
racters which separate them from each other. The right valve is
the flattest, and bears the ridges of the hinge.
Chemnitz gives the best character for the species, and has ob-
served the character furnished by the hinge, which has been over-
looked by Lamarck, and by all recent authors.

the cartilage, having a very small concavity in the inner surface
in front of the cartilaged process representing the sinus in Ano-
mia ; the left valve rather more convex, with aii oblong, trans-
verse pit for the internal cartilage under the umbo.

Anomia or Placuna sp. Desh. in Lamk. Hist. 2 ed. vii. 270, note.
This shell has all the external characters of the flat species of
Placuna, and has the same muscular impression ; but instead of
having the two linear, diverging ridges and grooves to give attach-
ment to the cardinal cartilage, it has an oblong, elevated process in
the right valve, and an oblong cavity in the left, exactly similar to
those found in the genus Anomia ; and on the inner surface of the
right valve, just in front of the base of the process which supports
the cartilage, there is a small, shallow, roundish pit, with a short
furrow towards the centre of the shell, which is evidently a rudi-
mentary representation of the sinus found in the genus Anomia.
This rudimentary sinus is not visible on the outer surface of the
shell.
PLACENTAD^.
O
This shell forms the passage between the genus Anomia, or rather
Placunanomia, and Placuna. It shows the gradual change which
takes place between the three genera. In Anomia there are two
muscles for the purpose of attaching itself to marine bodies, which
form a plug which is free from the sinus of the shell. In Placu-
nanomia there is only a single muscle to perform the same office,
and in the more typical species of this genus the plug itself is fixed
into the surface of the shell, forming, as it were, part of its substance.
In Hemiplacuna and Placuna there is no muscle or plug for attach-
ment, and the shells are free; but in Hemiplacuna there is a rudi-
mentary development of the sinus through which the plug is usu-
ally emitted, and the ligament which connects the shell is of the
same form as that found in the genera Anomia and Placunanomia.
The name for the genus is not consistent with the Linnasan ca-
non ; but used rather than burthen the genus with two names.

The European species of Anomiadm have been much multiplied,
while on the other hand the exotic species have been almost en-
tirely neglected.
The form, substance, surface and colour of the shell, which have
been used to distinguish the species, were suspected by Montague
to he dependent on the age of the specimens and the locality in
which they happened to be found, and further researches have
proved the accuracy of these observations.
Synopsis of the Genera.
1. Placunanomia. Shell not eared ; upper valve with two subcen-
tral muscular scars ; the anterior upper lobe of the notch agglu-
tinated to the cardinal edge ; plug shelly at the top and near
the body, to which it is attached, and with homy longitudinal
laminee below and internally.

2. Anomia. Shell not eared; upper valve with three subcentral
muscular scars ; the anterior upper lobe of the notch separated
from the cardinal edge ; the plug entirely shelly, and quite
free from the edge of the notch.
3. Limanomia. Shell eared on each side of the umbo ; sinus high
up near umbo. Muscular scars ? Fossil.
1. PLACUN ANOMIA.
Upper or dorsal valve with two subcentral muscular scars ; the up-
per scar radiately veined. Byssal notch distinct, converted into
a hole by the upper part of the anterior lobe of the notch being
soldered to and foiming part of the cardinal edge : the plug tri-
angular, gradually enlarging in size ; the apex and outer surface
next to the body to which it is attached, calcareous, longitudi-
nally striated ; the inner surface covered with horny, longitudinal,
parallel laminae, and more or less agglutinated to the edge of the
notch.

Mr. Broderip, who established this genus, does not observe the
character furnished by the muscular impressions, or the lobe of the
notch ; he merely says, “ Impressio muscularis in utraque valva
subcentralis. In valva superiore organ! adhesionis impressio super-
addita.” And further, that “ the organ of adhesion, which in its
bony character (for it is more bone than shell) resembles that of
Anomia, does not perforate the lower valve directly, but is inserted
between the laminas of the internal surface of the lovver valve, above
the muscular impression and below the hinge, and passes out into
an external, irregular, somewhat longitudinal, superficial fissure or
cicatrix, which is narrowest at the hinge margin, and which it en-
tirely fills to a level with the surrounding surface.’’
This form is produced by the gradual increase of the size of the
plug and the simultaneous increase of the size of the shell.
Some have considered the “ plug” or “ stopper” of Anomia to be
a third valve, which is evidently a mistake. Phillippi {Moll. Sicil.
ANOMIAD^.

i. 92) considers it as the ossification of the tendon of the adductor
muscle. Mr. Broderip, in the passage quoted, regards it as a hone.
In Dr. DieSeubach’s Travels Mr. Gray has remarked ; “ The plug
is evidently only a modification of the kind of laminar beard formed
by the end of the foot of the arcs {area) ; for, like it, it is formed of
numerous, parallel, erect, longitudinal horny laminEe, placed side by
side, extending from the apex to the margin, and it is on these
plates that the calcareous matter is deposited when the attachment
assumes its shelly substance. The same structure is to be observed
in the plug of the European Anomia Ephippiuni {striata).’' — Voy.
New Zealand, ii. 261.
Messrs. Forbes and Hanley compare it to the byssus of Pecten,
and predict that when the very young Anomiae have been observed,
they will be found to be attached by threads, like that genus {Brit.
Moll.). The plug of a very small specimen of the genus is laminar,
like that of the adult shell.
M. Philippi, when describing Pododesmus, appears to have ob-
served only the upper of the two muscular scars, for he gives as the
generic character, “ Irnpressio muscularis unica, ovata,” and he only
figures the larger upper one on the plate.
The upper scar, which is usually of a larger size, and has its sur-
face covered with radiating veins, while the lower is generally
punctated, appears to be the one which gives rise to the muscle
that is attached to the inner surface of the plug.
The examination of the upper valve of a large series of specimens
of Placunanomia patelliformis has shown that the position of the
two muscles is liable to a slight variation ; in by far the larger num-
ber of specimens the small lower muscle is quite close to and con-
fluent with the scar of the upper larger muscle, but in a few speci-
mens it is separated from the upper larger one by a small interval
or space. Hence probably the three West Indian species of the
genus may prove, when a larger series of specimens have been col-
lected and compared, only varieties of the same species.

joignent jamais. Ici au contraire le troa est complete, et la valve
est reellement perforee.’’ This character is common to all the spe-
cies of Placunanomia. M. Deshayes does not figure nor describe
the plug. The habitat, “Cagayan, Lucon,’’ assigned to this species
by Mr. G. B. Sowerby must be a mistake. It is the specimen refer-
red to by Mr. Broderip in the observations on the genus in the Pro-
ceedings of the Zoological Society.

This species is easily known from the other European species of
the family by being generally thicker and regularly radiately rib-
bed, and greenish ; but the number and position of the muscular
scars at once separate it from all the multiform varieties of that
species. Some authors, overlooking the latter character, have been
inclined to regard it as a mere variety of Anomia ephippium.

tremely variable in form, surface, colour and thickness, and they
also offer considerable variety in the disposition of the muscular
scar. In all the upper scar is largest, but variable in shape
from round to broad cordate. In most the two lower scars are close
together, but separate, and nearly on the same line. In others the
lower scar is rather lower than the middle one, and in a few (four)
specimens, which are mostly produced posteriorly, the lower scar is
much lower ; that is to say, in some the upper edge is parallel with
the lower edge of the middle one. In one specimen the two lower
scars are on the same line, and are confluent together, forming a
scar about the same size as the upper scar, yet showing that the
lower scar is formed by two muscles ; so that this valve cannot be
confounded with a Placunanomia.
The examination of this series of specimens from the same loca-
lity I think shows, that though the comparative size and disposition
of the scars may furnish good characters for the distinction of the
species, yet they are not to be relied on.

PREFACE.
The chief objects in forming the present Synoptical Cata-
logue have been, to exhibit at one view a complete list of all
the specimens of Brachiopodous Mollxjsca in the Bri-
tish Museum Collection, and to furnish such an account of
the species knovra to exist in other collections, but which
are at this time desiderata in the British Museum, as the
materials at hand would permit me to compile, in order to
enable travellers, collectors, and others, to assist in com-
pleting the national collection.
For this purpose, short descriptions have been given of
all the genera and species of recent Brachiopoda now known
to exist in the dilferent museums and private collections,
and of the better-known fossil species of the various fami-
IV
lies. At the end of each description is added the country,
or strata, and other peculiarities of each species mentioned.
Great attention has been paid to dates, and the generic
and specific names which appear to possess priority in this
respect have been adopted.
Keference has also been made to the works in which the
genera and species appear to have been first described or
noticed.
Mr. S. P. Woodward has kindly assisted in the pre-
paration of the Catalogue, especially as regards the fossil
species, and in dravring the illustrations, which have been
engraved by Miss Ann Waterhouse of the School of
Design.

Class 11. BRACHIOPODA.
Shell inequivalve, equilateral, attached by a muscular peduncle,
or by the surface of one valve, or free ; valves applied to the
dorsal and ventral sides of the animal, imited by muscles and
mostly articulated by teeth ; dorsal valve* usually smallest, always
free, furnished internally wdth sockets for the hinge-teeth, and
with shelly processes t for the support of the animal ; ventral
valve usually largest, and with its umbo produced and perforated
for the passage of the peduncle, frequently attached by its outer
surface, and generally provided internally with two prominent
teeth j periostracum thick, sometimes developed into concentric
lamellae.
Animal furnished with elongated labial appendages, or oral
arms, which are free or united by membrane and variously folded,
* 'Vt'hat is here called the dorsal valve has often been called the lower
valve, being usually below when the animal is in its natural position
attached to marine bodies ; but it has been found to cover the back of
the animal.

being usually spiral, and having their outer margin fringed with
cirri ; mantle-lobes closely applied to the valves, fringed with
horny seta, and furnished with large branching veins ; digestive
organs occupying a small space near the umbones, separated by
a strong membrane from the general cavity of the shell in which
the ciiTated arms are expanded; respiration performed by the
vessels of the mantle ; circulation effected by two hearts, each
having an auricle and a ventricle ; sexes united ? ; ova developed
in vascular sinuses, or in the large veins.

In 1798 M. Cuvier (Legons d’ Anatomic Comparee, Ann.vii. i.
tab. 5) placed the Brachiopods with Hyalaa in the thu-d dmsiou
of the shell-bearing ace])halous mollusca, which he afterwards
named Brachiopodes. Thus ;
1. Terebratules. Terebratula, Calceola, Hyalsea.
2. Lingules. Lingula.
3. Orbicules. Orbicula.
In 1812 Lamarck {Extrait du Cours, 8vo, p. 105) regarded the
Brachiopods as part of the Acephales testaces.
§ 1. Les Brachiopodes. Lingule, Terebratule, Orbicule.
§ 2. Ostracees. Radiolite, Calceole, Cranie, Anomie, and other
bivalve shells.
In 1815 Rafinesque {Analyse de la Nature, 12mo, p. 148) di-
vided the present Brachiopodes between the family Ostreacia of
the Bivalvia, subfamily Placunea. 1. Calceolina = Calceola,
2. Cranicella= Crania.
Family Brachiopea of Poleteria. 1. Orbicula. 2. Terebra-
tula. 3. Lingula.
In 1817 M. Cuvier {Reg. Anim. ii. and ed. 2, 1829, iii, 122)
considered Les Brachiopodes as a class containing
1. Les Lingules.
2. Les Terebratules (Spiriferes, Thecidees).
3. Les Orbicules (Cranies, Diseines).
In 1818 Lamarck {Hist. Nat. des Animaux sans Vertebres) re-
garded the Brachiopods as forming the gi-eater part of his third
section of the CoNCHiFkRES monomyaires,
1. Les Rudistes. 1. Spheruhte. 2. Radiolite. 3. Calceola.
4. Birostrite. 5. Discine. 6. Cranie.
2. Les Brachiopodes. 1. Orbicule. 2. Terebratule. 3. Lin-
gule.
In 1819 M. de Ferussac {Tabl. Syst. Moll. fol. 38) regarded
Les Brachiopodes as a class of the Acephales, and divided them
into
Fam. 1. Les Lingules. Lingule.
2. Les Terebratules. Terebratule, Magas.
3. Les Cranies. Orbicule, Cranie, Thecidee.

and placed Calceole in the family Rudiste of the class Lamelli-
branches.
In 1825 M. de Blainville [Manuel Malac. 8vo) divided the
class Acephalophores into four Orders ; the following contain what
are now considered Brachiopods.
Order 1. Palliobbanches.
1. Coquille symm&rique. Lingule, Terebratule, Thecidie,
Strophomene, Plagistome, Dianchore, Podopside.
2. Coquille non-symmetrique, irregulihre, constamment adM-
rente. Orbicule, Cranie.
Order 11. Rudistbs. Sphaerulite, Hippurite, Radiolite, Bi-
rostrite, Calceole.
In 1825 M. Latreille [Fam. Nat. Reg. Anim. 8vo, 196) divided
the Mollusques Agames Endocephales Brachiopodes into two
Orders and three Families, thus ;
1. Pedoncules. 1. Equivalves, lAngule. 2. Inequivahes,Te-
rebratule.
2. Sessiles. 1. Fixivalves, Orbicule, Cranie, Acarde, Sphseru-
lite. Placing the genus Calceole in the family Ostraces of Con-
chiferes.
In 1829 M. Rang [Manuel des Mollusques, 12mo, Paris, p. 257)
arranged the Acephales Testaces Brachiopodes thus :
I. Lingules. Lingule.
II. Terebratules. Terebratule, Strophomene, Thecidee, Cal-
ceole.
III. Cranies. Cranie, Orbicule.
In 1834 Leopold von Buch [Ueber die Terebrateln, Berlin,
4to) gives the following arrangement : —
A. Attached by the border.

In 1836 M. Deshayes {Lamk. Hist. Nat. Anim. sans Vert. vii.
309) proposed the following arrangement : —
Brachiopodes.
I. Valves articulees. — 1. Productes, Produetus. 2. Terebra-
tules, Terebratule. 3. Thecidees, Thecidee.
II. Valves libres. — 4. Lingules, Lingule. 5. Orbiculees, Or-
bicule. 6. Cranies, Calceola, Cranie.
Dr. Gray in 1840 {Synopsis Brit. Mus. 1840, i. f. 7) divided
the order thus
The family of Terebratulidee are regular, and somewhat like a
Grecian lamp in form, and have therefore been called Lamp-
shells. The valves are articulated together, and are attached by
means of a tendinous band, which passes out of the hole in the
apex of the upper valve as in Terehratula and Spirifer.
The Lingulida are attached by a tendinous tube, resembling
the stem of the Barnacles, which projects between the apices of
the gaping valves.
The Discinidw, on the other hand, have the tendon passing
out of a linear slit near the middle of the under valve.
And at p. 155 gives a list of the genera as follows ; —
1. Lingulidce, Lingula. 2. Terebratulidce, Terehratula, Spi-
rifer. 3. Productidce, Produetus, Calceola. 4. Thecideidee,
Thecidea. 5. Craniadm, Crania. 6. Discinidee, Discina.
In 1841 Mr. John Phillips {Figures and Descriptions of the
Paleeozoic Fossils, 8vo, p. 54) arranged the genera of Brachiopoda
thus : —
1. Valve free, attachment by exserted muscle.
A. Valves equal. 1. Lingula.
B. Valves unequal.
a. Larger valves imperforate, Athyridce; * no cardinal area,
Producta ; ** a cardinal area, Calceola.
b. Larger valve perforated in or under the beak.
Perforation reaching to the hinge-line, Delthyrida.
Cardinal area more or less common to both valves, Orthis.
Cardinal area confined to the large valve. * Internal plate of the
larger valves separate, Spirifera. ** Internal plates of the larger
valve united on the inside line of the shell, t Plate narrow,
Strigocephalus. ft Plates very narrow, Pentamerus.
Cardinal area obsolete, beak incm-ved over a minute perfora-
tion, which is often obtect, or merely serves to receive the beak
of the smaller valve, Cleiothyris.
Perforation not reaching to the hinge-line, Cyclothyridce.
* Beak truncate, perforate, Epithyris. ** Beak acute, the per-
foration below it, Hypothyris.

BRACHIOPODA.
In 1842 Dr. Gray {Synopsis Brit. Mus. 1842, 88) proposed
the following division for the class Brachiopoda : —
“ Some are attached by means of a tendinous cord, which
passes out between or in a groove in one of the valves. The
family of Lingulidce are attached by a tendinous tube, resembling
the stem of the Barnacles, which projects between the apices of
the gaping valves, as in Lingula.
“ The family of Terebratulidm are regular and somewhat
like a Grecian lamp in form, and have therefore been called
Lamp-shells. The valves are articulated together, and the
animals are attached by means of a tendinous hand, which passes
out of the hole in the apex of the upper valve, as in the Tere-
bratulae and Spirifer.
“ The family Discinidce, on the other hand, have the tendon
passing out of a linear slit near the middle of the under valve ;
the shell is suborbicular, and the upper valve conical, hke a
Patella, but more symmetrical — Discina.
“ Others are immediately attached by the outer surface of
their under shell.
“ The family of Craniadce are attached by their flat lower
valve, which has an obhque facet on the upper side ; the upper
valve is suborbicular, conical, with a subcentral apex like the
DiscincB : the muscular scars of the lower valves bear some re-
semblance to a face, hence the name of Crania.
“ The family of Thecideidce are fossil shells, very like the last,
but only attached by the apex of the lower valves, which is pro-
duced and somewhat lamp-hke, and the cavity is furnished with
a comphcated apparatus to support the internal organs, as in
TerebratulidcB — Thecidea.
“ The family of ProductidcB are fossils, probably aUied to the
latter ; one valve is concave, the other flat, or concave and pressed
into the cavity of the other ; the hinge-hne is straight and the
shell subs3Tnmetrical — Productus, Calceola.”
In 1846 Mr. W. King {Ann. 8f Mag. N. H. xviii. 1846, p. 28)
divided the genera of Palliobranchiata into the following fami-
lies : —
1. ObolidcB. 1. Obolus.
2. LingulidcB. 1. Lingula.
3. Orbiculida. 1. Orbicxda.

4. Caprinella.
3. Radiolidee. I. Radiolites. 2. Biradiolites. 3. Caprotina.
In 1848 Ur. Gray {Ann. §• Mag. N. H. 1848, ii. p. 435 ;
Translated Wiegm. Arch. 1849, 98, and Loven, Arsb. 1845-1849,
213) proposed the following arrangement : —
Brachiopoda. — Subclass 1. Ancylopoda.
The oral arms not extensile, or only at the tip ; on fixed
shelly supports, or in grooves in the under or ventral valves ; the
mantle is adherent to the shell, the substance of the shell being
pierced with numerous minute perforations, which are pervaded
by the processes of the mantle.
8
BRACHIOPODA.
Order I. Ancylobrachia.
The oral arms are attached to two shelly plates arising from
the hinder or cardinal edge of the ventral valves ; they are re-
curved and convolute on the inner side of the lamina. The animals
are generally attached to marine bodies by a tendinous peduncle,
which passes through a hole in the top of the umbo of the larger
or dorsal valve ; this peduncle and the hole are sometimes obli-
terated in the older specimens.
The order only contains a single family,
Fam. 1 . Terehratulidw,
which is nearly synonymous with the smooth Terebratula of
Sowerby, the perforated Terebratula of Carpenter, the genus
Epithyris of Philhps and Terebratula of King, the family Tere-
bratulida of M‘Coy, and Cyclothyridce of Phillips.
The animal has been described by Linnaeus, Pallas, Ow'en,
Blainville, Philippi, D’Orhigny and others. In some genera the
hoops are united together below by a transverse band which is
attached to medial longitudinal ridges of the ventral valve, as in
Terebratula of Retzius = the Terebratella of D’Orbigny, as T.
dorsata and Magas, Sow. In others the hoop forms a ring, and
is free from the ventral valve, as Gryphus, Megerle^ Terebratula,
D’Orb. and Terebratulina, D’Orbigny, for T. vitrea and T. caput
serpentis. D’Orbigny indicates other genera under the names of
Terebrirostra and Fissirostra.
Order II. The Cryptobrachia
have the oral arms entirely attached in the form of two or more
lobed processes sunk into the grooves in the disc of the ventral
valve. They are generally thick shells. This order also con-
sists of only a single family.
Fam. 1. Thecideadee.
The animals are described by Phihppi and D’Orhigny. The
genus Argiope, De Longchamps = Megathiris, D’Orb. {Tereb.
detruncata) is attached by a tendon passing out of a very large
perforation below the beak of the dorsal valves : Philippi con-
founds this genus with his Orthis, which is different from the
Orthis of Dalman. Thecidcea has the shell attached by the trun-
cated apex of the dorsal valve, or it is free w'hen the apex is pro-
duced and entire. De Longchamps, who estahhshed the genus
Argiope in 1839, pointed out the affinity of this genus to The-
cidcea.
Subclass 2. Helictopoda.
The oral arms are elongate, regularly spirally twisted when in
repose. The mantle-lobes are merely appfied to the inner surface
BRACHIOPODA.
9
of the shell, and the substance of the valves is not pierced with
minute perforations, though the sm-face is sometimes spinulose,
the spines being only formed on the edge of the shell while it is
being increased in size.
Order III. Sclerobrachia.
The oral arms support a shelly band arising from the hinder
or cardinal edge of the ventral valve.
Fam. 1. Spiriferida.
The oral arms very largely developed and supported the whole
of their length by a thin shelly ? or cartilaginous ? spirally twisted
plate.
These shells are only known in the fossil state, hut the spiral
supports of the arms are generally preserved, and may be dis-
covered by sections of the fossil, and are often to be seen in the
fractured specimens.
This family is equivalent to the genus Spirifer of J. Sowerby
the father, the family Delthyrida, M‘Coy, who gave some ex-
cellent illustrations of the structure and the Spiriferidee of King.
D’Orbigny proposed some genera under the names of Spiriferina,
Spirigera and Spirigerina, according to the direction of the axis
of the spiral cones, but it is douhtfid if these genera are only new
names to those already established.
The Spirifer of Sowerby, as reduced by M‘Coy, and the Mar-
tinia of M‘Coy, have the hinge as long or longer than the width
of the shell. In Atrypa, Dalman, and Athyris, M‘Coy, it is
shorter and the shells oblong, rounder behind.
According to the description of Mr. King, the genus Strigo-
cephalus would appear to form the passage between this and the
next family {Ann. Nat. Hist. xvui. 89).
Fam. 2. RhynchonellideB .
The oral arms are elongate, fleshy, supported at the base by
two short, hard, diverging shelly laminae arising from the hinge-
margin of the ventral valve.
They are easily known from the Terebratulidm by the cavity of
the shell being without shelly plates, its substance not perforated,
and its surface being generally radiately plaited.
Only one species, T. psittacea, is known in the recent state ;
its animal has been described by Professor Owen. The family
is equivalent to the plaited Terebratula of the elder James Sowerby
and Von Buch, the non-perforated Terebratula of Carpenter, the
genus Hypothyris of Phillips, and part of the family Terebratu-
lidce of King. It contains the genus Rhynchonella of Fischer and
D’Orbigny = Hypothyris of Phillips ; Camerophoria, King ;

BRACHIOPODA.
t/Hcifes, Defrance?; Tn^'owosemwSjKcEiiig; ilAywc^ora, Dalman ;
Pygope, Link ; Delthyridaa, M‘Coy ; Pentamerus, Sowerby.
Order IV. Sarcicobrachia.
The oral arms fleshy to the base and without any shelly sup-
port ; the lower valve without any processes on the hinge-margin
or disc, or except sometimes a shght medial longitudinal elevation.
Fam. 1. Productidee
consists entirely of fossil species, some much resembling those
of the former family, but the shells are generally spinose ; they
are only attached to marine bodies by the surface of the ventral
valve, as the genera Productus, Sow. ; Strophalosia, King ; Cho-
netes, Fischer; Leptmna and Orthis, Dalman; Strophomena,
Rafinesque ; and Calceola, Lamk. This family comprises Mr.
King’s ProductidcB, Strophomenida and Calceolide.
Fam. 2. Craniada.
Nearly allied to the last, but the upper valve is simply conic
like Patella, and the animal is attached by the outer surface of
the ventral valve.
The animal has been figured by Muller, Poli and others. It
includes the recent genus Crania of Retzius, including the Or-
bicula of Lamarck, Criopus of Poli. The lower valve of the only
recent species I am acquainted with varies greatly in thickness
and form according to the position and habitation of the animal.
This animal in many particulars is alhed to ThecidceadcB.
Fam. 3. Discinida.
The upper valve is conical and patelloid, the lower orbicular,
and is attached to marine bodies by a short tendinous peduncle,
which passes out through a slit in the hinder part of the disc of
the ventral valve.
The animal of this genus has been described by Mr, Owen
under the name of Orhicula, Mr. G. B. Sowerby having some
years ago confounded this shell nith that genus, which has caused
confusion, which has existed to this day. The shell was first de-
scribed by Schumacher as a section of the genus Crania. Mr.
King, probably misled by this mistake, does not include it in his
arrangement. This shell is peculiar, for being homy rather than
a shell texture, it is flexible when moist.
Fam. 4. Lingulidts.
The valves are nearly equal elongate, and supported by a thick
peduncle which comes out between the beaks of the two valves.
The shells are covered with a horny periostraca, and in some
species the shelly matter is so very thin that the shells are flexible
BRACHIOPODA.
il
and nearly entirely cartilaginous. The family consists only of a
single genus. Lingula.
Order V. Rudistes.
This Order has been placed by modern authors with the Bra-
chiopoda : the proofs of its belonging to this family are not very
evident ; but as there is no other to which they appear to be more
nearly allied, they may as well be retained in this position.
Lamarck, Cuvier, Ferussac, and some other authors have re-
garded some of the genera as belonging to Cephalopoda, and
others as Bivalves (Conchifera). Deshayes regards them as more
neai-ly allied to Chama, the character of the family having been
lost by the destruction of the inner coat of the shell during the
fossilization of the specimen.
M. d’Orbigny has properly united them into one group under
the name of Irregular Brachiopods or Rudistes, but he includes
with them the genus Crania, which is a true Brachiopod.
They form three very distinct families.
Fam. 1. Radiolitidce.
The lower valves more or less elongate-conical, fixed; the
upper valve conical or spiral, free ; the texture of the lower valve
cellular or fibrous.
The Radiolites has the upper valve flat or conical and cap-like.
The Caprina, D’Orb., has a spiral and produced upper valve.
The first of these genera has had many names applied to it, but
that given by Lamarck has the priority. It has been called
Sphmrulites, Ostracites and Acardo, and the cast of the interior
cavity has been considered as a genus, under the name of Biros-
tris and lodamia.
Fam. 2. Hippuritidm.
The lower valve is elongate, tapering sub-cyhndrical, of a solid
laminated texture ; the upper valve is nearly flat, and pierced
with pecuhar pores radiating to the circumference with branches
diverging to the upper surface.
This family contains only a single genus, Hippurites, Lamarck,
which has also had many other names applied to it, as Cornu-
copia, Orthoceratites, BatoKtes (or Batholites), Raphanister, and
Bitubulites.
Fam. 3. Caprotinidm.
The lower or fixed valve is conical and spirally twisted, and
marked internally with prominent ridges or transverse septa ; the
dorsal or free valve is oblique or sph-al. They differ from Ca-
prina in the valves not being of a cellular or fibrous texture.
This family contains two genera ; —
1. Caprotina, D’Orb., which has the cavity of the shell merely
marked with internal ridges.
12
BRACHIOPODA.
2. Ichthyosarcolites has the cavity of the large spiral or invo-
lute fixed valve divided transversely hy a number of oblique septa ;
the upper valve is probably like an operculum, but this genus is
very imperfectly knovrn.
In 1849 Dr. H. G. Bronn {Index Talesontologicus, 8vo, p. 210)
divided the Brachiopoda thus : — •

Fam. 1. TEREBRATULIDiE.
Shell minutely punctate, usually round or oval, and smooth
or striated ; ventral valve (fig. 2) largest, its umbo produced into
a beak with the apex truncated and perforated ; foramen [f) sepa-
rated from the hinge-line by a small triangular plate or deltidium
(d) composed of two pieces (deltidia) ; teeth {t) situated one on
each side of the deltidium, supported by plates ; dorsal valve
(fig. 1) with a depressed umbo; furnished interiorly with a pro-
minent cardinal process (j) between the sockets for the teeth (t’),
a hinge-plate (p) with four cavities and a central ridge or septum
(s) ; internal skeleton in the form of a slender shelly loop, at-
tached by its crura (c) to the hinge-plate, and furnished near its
origin with oral processes (c).

Animal always attached by a peduncle ; furnished with cirrated
arms, united throughout by membrane, folded upon themselves,
and only spiral at their extremities ; muscles of three kinds, —
adductors, retractors, and those which go to the peduncle [byssal
or pedal muscles of ordinary bivalves). The adductors are at-
tached to four spots near the centre of the dorsal valve {m), and
to a single spot behind the centre of the opposite valve {a) ; the
retractors originate on each side of the adductor in the ventral
valve (r), and are attached to the cardinal process (j) of the dorsal
valve ; the hinge-teeth form the fulcrum on which the dorsal
valve turns ; of the pedicle muscles, two (p) originate outside the
adductor and behind the retractors in the ventral valve ; two

BRACHIOPODA.
Others, each with a double termination, are inserted in the hinge-
plate {p) of the dorsal valve ; the septum supports the visceral
membranes.
The position at which the intestine of Terehratula terminates,
namely just behind the adductor muscle (fig. 2, v), seems to
imply that it discharges through the byssal/oramew ; and as the
same arrangement exists in Terebratulina, Kraussia, Argiope, and
in the recent Rhynchonella nigricans, it becomes probable that
such is the general rule ; in those extinct genera which have the
foramen closed at an early age, there is always an opening be-
tween the deltidium and the umbo of the smaller valve (e. g. in
Uncites gryphus), which has been mistaken for a byssal notch.
The foramen in the hinge-plate of Athyris shows that the intes-
tine took the same course in the Spiriferidce as it is known to do
in the Rhynchonellida and Terebratulida *. ,

Albany Hancock.

The extent of the septum may be readily ascertained in fossil
species by a little acid, without injuring the specimens.
The sections into which Waldheimia has been groujted depend
entirely upon modifications of external form.

Mr. James Sowerby the elder gives a “ partial longitudinal
septum with appendages attached to the hinge within,” as the
character of the genus Magas, which is that of the whole tribe.
He first pointed out the advantage of studying the internal ap-
paratus, and observed in 1816, “ It is much to be washed that
some person w'ould publish an account of the curious internal
appendages of these shells.” — Mineral Conch, t. 119.
M. de |Blainville in 1828 (Diet. Sci. Nat. liii. 145) used the
form of the internal apparatus to divide the Terebratulee into six
divisions. Section A. “ Gripus, Megerle” = Terebratulinina.
B. = Terebratella. C. = Terebratulinina. D. = Megerlia.
E. = Bouchardia. F. = Argiope.
The genera into w'hich the Magasina have been divided depend
chiefly on modifications of the internal skeleton ; these do not
always correspond with the peculiarities of external form, or the
character of the foramen and deltidium.

The Megerlia often resemble Argiope in shape, and in having
corresponding ribs ; the denticulation of the internal margin of
the valves in some species may be compared with the larger mar-
ginal processes of the latter genus.
